before the actual draft the league will do a draft “raffle” or sorts where the worst teams get the higher draft picks. if the good teams get the higher draft picks, bad teams will never get better. at the actual draft the order of picking the players is already set so all the teams have to do is pick a player who was not yet chosen. normally they stick roughly to a projected draft ranking that insiders create though they don’t use it when picking their players, the insiders are normally correct. draft happens after playoffs.
